My check engine light came on and it has two active codes. They are both P0023. One says "P0023" and the other says "P0023 P".
When I start it from a cold start, it will idle rough and accelerating does not help to smooth it out. Once I start driving, the car runs smooth and I cannot tell that anything is wrong.
Due to me driving my work truck, I have only put 14,000 in two and half years. Maybe the problem was caused by it sitting too long?
I am going to try to change whatever it is myself (unless it just has to be done at the dealer) to save myself some money. So I am curious if anyone knows what the code might be and what part or sensor I might need?
Thank you in advance for your help.
have the same problem?
